PHP创建表1个阵列通过数组索引操作

Question

我有这个数据库：

 
+----+------------+------------+-----------+----------+---------+------+-----------------+----------+------------+ 
| id | reservedby | date  | timestart | duration | endtime | cost | details   | status | dateadded | 
+----+------------+------------+-----------+----------+---------+------+-----------------+----------+------------+ 
| 1 | enerva  | 09/29/2013 | 9-10am | 3  | 11-12pm | 1500 | basketball dre! | pending | 0000-00-00 | 
| 2 | mangkanor | 09/30/2013 | 9-10am | 8  | 5-6pm | 4000 | Sabong Dre!  | approved | 0000-00-00 | 
+----+------------+------------+-----------+----------+---------+------+-----------------+----------+------------+ 

我用它在我的表：

正如你可以看到，9上午10点位置由Evava预留;那个小时的持续时间是3，意思是'3小时'，所以结束时间是11-12点。但是，在我的表格中，我不能在上午10点到11点和下午11点到12点加入'Not Available, taken by: enerva'字符串。

这里是我的代码：

<?php 
if (isset($_GET['checkdate'])) { 
    $date = urldecode($_GET['date']); 
    echo "<br/><br/><h3>Reservations</h3>"; 
    echo $date; 
    $timearray = array("8-9am","9-10am","10-11am","11-12pm","12-1pm","1-2pm","2-3pm","3-4pm","4-5pm","5-6pm","6-7pm","7-8pm","8-9pm","9-10pm","10-11pm"); 
    $tablecolor = 1; 
    echo "<table style='width: 90%;'>"; 
    echo "<tr>"; 
     echo "<th>"; 
      echo "Time"; 
     echo "</th>"; 
     echo "<th>"; 
      echo "Status"; 
     echo "</th>"; 

    echo "</tr>"; 
    foreach ($timearray as $timearrays) { 
     if($tablecolor %2 == 0) { 
      echo "<tr>"; 
     } 
     else { 
      echo "<tr style='background-color: rgb(0,100,255); background: rgb(0,100,255);'>"; 
     } 

      echo "<th>"; 
      echo "<h3>$timearrays</h3>"; 
      echo "</th>"; 
      echo "<td>"; 
      $sql = "SELECT * FROM reservation WHERE date = '$date' AND timestart = '$timearrays'"; 
      $result = mysql_query($sql); 
      if(mysql_num_rows($result) == 0){ 
       echo "<a href='#'><h3 style='color: rgb(255,0,0);'>Reserve</h3></a>"; 
      } 
      else { 
       while($row = mysql_fetch_array($result)) { 
        $reservedby = $row['reservedby']; 
      } 
       echo "<h3>Not Available, taken by: $reservedby.</h3>"; 
      } 
      echo "</td>"; 
     echo "</tr>"; 
     $tablecolor++; 
    } 
    echo "</table>"; 
} 
?> 

我猜我必须在每次循环使用一个计数器的时间和减少它趋向于零。计数器不为零时，表格将显示'not available, reserved by: enerva'字符串;一旦达到零，它将显示'reserve'链接。但我找不到办法。

有没有什么办法或者其他的方式来做到这一点？我应该看看indexof数组，找出starttime和endtime两个索引之间的区别吗？

Answer 1

试试这个

else { 
    while($row = mysql_fetch_array($result)) { 
     echo "<h3>Not Available, taken by: $row[reservedby].</h3>"; 
     echo "</td>"; 
     echo "</tr>"; 
    }    
}

从你的回答我的评论，它不会是本身有问题，但你可能要显示无论是在不同的列同时保留（有点棘手，在现有处理代码）或只是在相同的<td></td>中，用<br />分开。这是我会去的，是一种懒惰有时:)

为了您的具体问题，只需使用duration列在你的数据库中while循环与增量计数器：

$i = 1; 
while ($i <= $row['duration']) { 
    echo 'Not available'; 
    $i = $i+1; 
} 

有点过于简单化，但它应该做的伎俩。

在您的并发预留问题上，实际上最好更改数据库（如果您不想以此方式工作，则不是“重构”）：因为所有时间间隔都是1小时，只需输入开始时间以24小时格式，并将您的sql查询更改为"SELECT * FROM reservation WHERE date = '$date' ORDER BY timestart;"。使用多维数组，您可以将该键与开始时间进行比较，并且仍然像以前一样显示时间段。

编辑： 找到一种方法，以更快的方式提供帮助。您只需在数据库中以24小时格式输入开始和结束时间，以便下面的代码工作。如前所述，我没有时间去测试它，但我不知道它会在哪里失败。

<?php 
if (isset($_GET['checkdate'])) { 
    $date = urldecode($_GET['date']); 
    echo "<br/><br/><h3>Reservations</h3>"; 
    echo $date; 
    $timearray = array(8,9,10,11,12,13,14,15,16,17,18,19,20,21,22); 
    $tablecolor = 1; 
    echo "<table style='width: 90%;'>"; 
    echo "<tr>"; 
     echo "<th>"; 
      echo "Time"; 
     echo "</th>"; 
     echo "<th>"; 
      echo "Status"; 
     echo "</th>"; 

    echo "</tr>"; 
    foreach ($timearray as $timearrays) { 
     if($tablecolor %2 == 0) { 
      echo "<tr>"; 
     } 
     else { 
      echo "<tr style='background-color: rgb(0,100,255); background: rgb(0,100,255);'>"; 
     } 

      echo "<th>"; 
      if ($timearrays == 8) {echo "<h3>8-9am</h3>";} 
      //Develop your timeslots here to display as required 
      echo "</th>"; 
      echo "<td>"; 
      $sql = "SELECT * FROM reservation WHERE date = '$date' AND timestart >= $timearrays AND endtime <= $timearrays;"; 
      $result = mysql_query($sql); 
      if (mysql_num_rows($result) == 0) { 
       echo "<a href='#'><h3 style='color: rgb(255,0,0);'>Reserve</h3></a>"; 
      } else { 
       echo "<h3>Not Available, taken by: $reservedby.</h3>"; 
       while($row = mysql_fetch_array($result)) { 
        echo "<br />" . $row['reservedby']; 
       } 
      } 
      echo "</td>"; 
     echo "</tr>"; 
     $tablecolor++; 
    } 
    echo "</table>"; 
} 
?>
